oil filter $8 oil$7qt all three o,rings $1 all bought at the same place same time.think about it

 

I take a close look a mine. If there's nothing obvious, I re-use them. Always have. Never had a problem. Go to a hardware store and buy a bag load of them for when you do need to replace them. They're pennies.

 

$3.30 for all three o-rings. Why take the chance. Just do it and save yourself a headache

 

re-use if in good condition and always add thread tape. Never had a leak from that......

 

Yeah but he changes his fluids thus having to remove his plug and derby cover!

 

+1 I always check them every oil change and if I see any visiable defect then it goes. Like the others have said you can buy them for hardley anything and keep about 10 on hand and replace them when they need it. Keeping it in top shape will keep peace of mind. I also check the Trany dip stick O ring also. Ride safe.

 

a word of caution on buying your o-rings from a harware store,make sure they are the same or suitable material compared to stock,being an industrial maintenence man I know all O-rings are not created equal. Having said that my last bike had 30k on it when I sold it and I only replaced the O-ring on the oil plug once. I have a magnifying worklight on my bench and you can see plenty good enough with that to tell if your O-ring is good or bad,anyone with good eyesight should be able to see a defect big enough to leak. As someone else said common sense is a good thing to use.

 

Since the o-rings are so cheap, I say why not change it?

 

I've never bothered. Clean them, check them, reuse them if they're good. I also use white Loctite on the threads of the drain plugs.

 

Too inexpensive to ponder, I replace them every time.
